power consumption

Power consumption refers to the amount of electrical energy used by devices or systems over time. It is measured in units called watts (W) or kilowatts (kW), indicating how much energy a device needs to operate. Higher power consumption means more energy use, which can affect utility bills and overall energy resources. For example, a running fan might use 50 watts, while a refrigerator may use 200-800 watts. Efficient devices use less power to perform the same function, helping save energy and reduce costs. Understanding power consumption helps manage energy use responsibly and efficiently.
